High efficiency task lighting fixture

Abstract

A task light fixture adapted for magnetic attachment to the underside of a shelf or cabinet above a work surface, the fixture having a reflector adapted to produce an asymmetric beam of light directed toward the work surface, the reflector being rotatable about a vertical axis to direct the light to various areas of the work surface.

I claim: 
     
       1. An adjustable lamp fixture comprising a housing having a top wall and a bottom wall parallel to said top wall, said bottom wall having a circular opening therein; a light concentrating, asymmetric open reflector having a circular flange thereon adapted for mating engagement with said bottom wall for rotatably mounting said reflector in said bottom wall to allow rotational adjustment of said reflector relative to said housing about an axis perpendicular to said bottom wall while maintaining said flange parallel to said bottom wall; and,   socket means adapted for receiving an elongated lamp for mounting said lamp in a position such that the longitudinal axis of the lamp is parallel with the bottom wall of said housing.   
     
     
       2. An adjustable lamp fixture according to claim 1 wherein said reflector is provided with a generally vertical arcuate section, said socket being positioned in said reflector such that an elongated lamp mounted in said socket is positioned to produce an asymmetric beam of light parallel to the lamp axis and opposite the generally vertical arcuate section. 
     
     
       3. An adjustable lamp fixture according to claim 1 wherein said reflector is provided with a first, generally vertical arcuate section, the concave surface of which is positioned to reflect light from the elongated lamp mounted in said socket back toward the lamp in a generally downward direction, said reflector having second and third substantially planar sections above the lamp to direct light from the lamp both left and right of the lamp in a generally downward direction and fourth and fifth substantially planar sections disposed at a relatively shallow angle relative to the bottom wall of said housing to direct light in the same general direction as said first reflector section, said reflector sections being adapted to direct light from an elongated lamp mounted in said socket in a generally downward direction to provide high intensity, even, glare free illumination. 
     
     
       4. An adjustable lamp fixture according to claim 3 wherein said reflector is provided with downwardly projecting lamp engagement means to position said lamp relative to the reflecting surfaces of said reflector.
